These water results from the City of Kirkland's water supply sampled by Aaron Young of AmTest, INC. The pre-treatment results are directly from a sink faucet in AmTest's laboratory. The post-treatment samples are from the same faucet after running through the DAWS system.  There was no introduction of any chemicals or outside treatment other than the DAWS filtration system.

Lab Report  Term Explanations:

1. MCL. Maximum Contamination Level. Although the values of the materials tested were below the maximum contaminate level threshold, the DAWS system significantly reduced the levels of these materials (as indicated by the percent of change on the report)
2. Hardness Chart.
3. TON. Threshold Odor Number is derived by the number of times water must be diluted before odor is eliminated.
4. Many Material present in the water supply have suggested guideline levels, but are considered in limited quantities non-hazardous and do not have MCL values. Some of these materials are: hardness, odor, residual chlorine and sulfur.

The hardness of water is referred to by three types of measurements: grains per gallon, milligrams per liter (mg/L), or parts per million (ppm). typically, the water produced by Fairfax Water is considered "moderately hard" to "hard." The table below is provided as a reference.

Water Hardness Scale

Grains Per Gallon Milligrams Per Liter (mg/L) or Parts Per Million (ppm) Classification
less than 1.0 less than 17.1 Soft
1.0-3.5 17.1-60 Slightly Hard
3.5-7.0 60-120 Moderately Hard
7.0-10.5 120-180 Hard
over 10.5 over 180 Very Hard
